NAME
gdalmdiminfo - Reports structure and content of a multidimensional
dataset
SYNOPSIS
gdalmdiminfo [--help-general] [-oo NAME=VALUE]* [-arrayoption NAME=VALUE]*
[-detailed] [-nopretty] [-array {array_name}] [-limit {number}]
[-stats] <datasetname>
DESCRIPTION
gdalmdiminfo program lists various information about a GDAL supported
multidimensional raster dataset as JSON output. It follows the follow-
ing JSON schema
The following command line parameters can appear in any order
-detailed
Most verbose output. Report attribute data types and array val-
ues.
-nopretty
Outputs on a single line without any indentation.
-array {array_name}
Name of the array used to restrict the output to the specified
array.
-limit {number}
Number of values in each dimension that is used to limit the
display of array values. By default, unlimited. Only taken into
account if used with -detailed.
-oo <NAME=VALUE>
Dataset open option (format specific). This option may be used
several times.
-arrayoption <NAME=VALUE>
Option passed to GDALGroup::GetMDArrayNames() to filter reported
arrays. Such option is format specific. Consult driver documen-
tation. This option may be used several times.
-stats Read and display image statistics. Force computation if no sta-
tistics are stored in an image.
New in version 3.2.
C API
This utility is also callable from C with GDALMultiDimInfo().
